Patients who underwent fusion, laminotomy, discectomy, or complete facetectomy were excluded. The patients' preoperative symptoms and comorbidities were also obtained from their medical records.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Over an average follow-up period of 46.8 months, of 500 patients who had undergone laminectomy at 1, 2, or 3 levels, 81 patients (16.2%) developed subsequent spinal disorders that required a reoperation. A multiple logistic regression analysis identified smoking as an independent predictor of reoperation (OR 2.15, p = 0.01). Smoking was also an independent predictor of reoperation after a single-level laminectomy (OR 11.3, p = 0.02) and after a multilevel (that is, involving 2 or 3 levels) laminectomy (OR 1.98, p = 0.05). For 72 patients undergoing reoperation only for spinal degeneration, smoking remained an independent, statistically significant predictor of reoperation (OR 2.06, p = 0.04). Nine patients underwent reoperation for nondegenerative conditions (hematoma, wound infection, or wound dehiscence), and in these patients, chronic obstructive pulmonary disease was the only statistically significant predictor of reoperation (OR 8.92, p = 0.03).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Smoking was the strongest predictor of reoperation in patients who had undergone single-level laminectomy, multilevel laminectomy, or reoperation for progression of spinal degeneration. These findings suggest that smokers have worse outcomes of lumbar decompression than nonsmokers.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2014.10.spine14186","type":"journal-article","created":{"date-parts":[[2015,1,2]],"date-time":"2015-01-02T14:59:58Z","timestamp":1420210798000},"page":"288-293","source":"Crossref","is-referenced-by-count":52,"title":["Smoking as an independent predictor of reoperation after lumbar laminectomy: a study of 500 cases"],"prefix":"10.3171","volume":"22","author":[{"given":"Mohamad","family":"Bydon","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"},{"name":"Johns Hopkins Spinal Biomechanics and Surgical Outcomes Laboratory, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"Macki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"},{"name":"Johns Hopkins Spinal Biomechanics and Surgical Outcomes Laboratory, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"De la Garza-Ramos","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"},{"name":"Johns Hopkins Spinal Biomechanics and Surgical Outcomes Laboratory, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel M.","family":"Sciubba","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Paul","family":"Wolinsky","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziya L.","family":"Gokaslan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"},{"name":"Johns Hopkins Spinal Biomechanics and Surgical Outcomes Laboratory, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy F.","family":"Witham","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Bydon","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine; and"},{"name":"Johns Hopkins Spinal Biomechanics and Surgical Outcomes Laboratory, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-spine14186","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"2623","DOI":"10.1097\/00007632-200112010-00018","article-title":"Smoking as a predictor of negative outcome in lumbar spinal fusion","volume":"26","author":"Andersen","year":"2001"},{"key":"b2-spine14186","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1015","DOI":"10.1097\/00007632-199109000-00001","article-title":"1991 Volvo Award in Clinical Sciences.
